virginiadot.orgAggregate gradation (sieve analysis) is the distribution of particle sizes expressed as a percent of the total dry weight. Gradation is determined by passing the material through a series of sieves stacked with progressively smaller openings from top to bottom and weighing the material retained on each sieve. Sieve numbers and sizes most often

1. Watershed Management Concept and Principles
oar.icrisat.orgwatershed, and small watersheds aggregate together to become larger watersheds. Water travels from headwater to the downward location and meets with similar strength of stream, then it forms one order higher stream as shown in Figure-2. The stream order is a measure of the degree of stream branching within a watershed.
